Filed May 21, 1953, Seri No. 736,735 3 Claims. 01. 28-21) My inventionrelates generally to hankers and specifically to cord or rope bankingdevices.

It is among the objects of my invention to provide a means for making abank of cord or similar material by forming a group of longitudinalstrands and then applying a finishing wrapping latitudinally. 7

It is a further object of my invention to provide an apparatus that willautomatically form a hank.

Yet another object of my invention is to provide a banking that israpid, neat, and accurate.

Another object of my invention is to provide a hanker which willformbanks of cord, rope, line, strands, filaments, wire, and other long,flexible materials which are diflicult or inconvenient to handle unlessthey are neatly formed into hanks.

Yet another object of my invention is to provide an apparatus that willspin a cord (or similar material) around and onto a pair of hankingbrackets, and will then rotate the brackets to spin the cord into alatitudinal wrapping. Y

A still further object of my invention is to provide an apparatus thateliminates labor costs in forming hanks and increases unit production byeach operator.

These objects and advantages as well as other objects and advantages'maybe achieved by the device shown, by way of illustration of my invention,in the drawings in which:

Figure 1 is a front elevational view of the apparatus;

Figure 2 is a rear elevational view of the apparatus;

Figure 3 is. a side elevational view of the apparatus;

Figure 4 is a side view of a safety cut-off portion of the apparatus,partially activated;

Figure 5 is an electrical control circuit for the apparatus;

Figure 6 is a side view of the safety cut-oft shown in Figure 4,completely activated; and

Figure 7 is a top plan view of the apparatus.v

The banking apparatus, in broadest terms, is a pair of stationaryhankingarms around which a cord is longitudinally wrapped'by being fedfrom a rotating drum. When a sufficient number of longitudinal strandshave been Wrapped around the banking arms, the arms begin to rotateaxially so that alatitudinal finishing wrap of cord is applied to thehank.

Referring now .to the drawings in detail, my rope hanking apparatus hasa table 11. An electric motor 12 is mounted under the table 111. A belt13 connects the motor 12 to drive the shaft 14. A gear 15 is mounted oneach endof the shaft 14. The shaft 14 is mounted at both ends on ahousing '16. Immediately above the shaft 14, two short shafts 17 for thehanking arms 18 are mounted, on the housing 16 at each end of the shaft14. Theshafts' jll each carry a large gear 19 engaged with thegears"15,'15;'whereby the hankin'g arms, 18,, 18 are rotated. The end ofone banking arm 18 is cleftto receive and frictionally engage the end ofa piece of rope or cord. The one of the hanking arm shafts *17 isconnected by a chain 20 to a revolution counter control 21.

A second motor 22 is mounted under the table 11. A belt 23 connects themotor to the shaft 24, which is mounted on the housing 16. This shaftdrives a chain 25 which operates a second revolution counter control 26.An electric clutch 61, normally disengaged, is connected to the shaft24, and when engaged, drives the coaxial shaft 27 which normally freelyrides on the shaft 24. Mounted on the shaft 27 is a gear 28 which drivesthe gear 53.

The housing .16 carries four double support bearings 51, 51, etc. whichperipherally support a rotatable drum 52. The drum is joined to or madeintegral with the large gear 53 and has two tracks 50 for support by thebearings 51. The gear 53 engages a smaller idler gear 54, which in turnengages another gear 55 on the outer shaft 56. The outer shaft 56normally rides freely on the inner shaft 49. On the end of the innershaft 49 there is a larger gear 57 (Figures 2, 3, and 7). This gearengages a worm 58 mounted on the shaft 59. The shaft 59 carries a gear60 which in turn engages the gear 19. Consequently, the motor 12 whichoperates the hanking arms 18, 18 also drives the drum 52, but only whenthe normally disengaged clutch 62 engages the outer and inner shafts 49,56 together.

An electric clutch 61 on the shaft 24 will engage and disengage themotor 22 from exerting its driving force on the gears 28 and 53. Anotherelectric clutch 62. dis engages the motor 12 from exerting its drivingforce on the gear 53. Still another electric clutch 63 disengages themotor 12 from driving the banking arms 18. An electric brake 64 stopsthe rotation of the arms 18, 118. The drum 52 carries a cord or ropefeeder 65.

A safety cut-off 66 in series with the clutches 61, 62, 63 is providedto prevent damage to the apparatus by jamming of the feeding cord 67 ifa knot should develop and prevent the cord from feeding. A plate 68carried by two bolts 69, 69 is mounted on a bracket 70. Springs 71, 71carried by the bolts 69, 69 normally urge the plate 68 away from thebracket 70. A pair of normally closed. electroswitches 72, 72 aremounted on the plate 68. When a knot 73 forms on the cord or rope 67, itcannot pass through the hole in the plate 68, and it presses the plate68 to overcome the springs 71, 71. This moves the plate 68 inwardly andthe contact pins 74, 74 engage the bracket they open the power circuitto disengage the clutches 61, 62, 63 thereby stopping the apparatus,until the knotted cord is unknotted and-the pins 74 re.-. stored tonormal position. a a l 1 The apparatus is ready, for operation when theclutch. 61, clutch 62, and clutch 63 are disengaged. The brake. 64 isset to hold the apparatus immobile. The end of the cord 67 is passedthrough the safety cut-off 66, through the cord feed 65, and is engagedwith the end of the: arm 18. The starter switch 75 is pressed, whichengages the clutch 61. This causes the drum to rotate asthe brake 64 isreleased. The drum 52 rotates, wrapping the cord 67 into thelongitudinal'strands 76 forming the longitudinal portion of the hank.When the counter 26 has counted off a predetermined number'- of strandsas" havingbeen wrapped around thehanking arms 18, 18, the clutch 6 1 isdisconnected by being 'deenergized by the counter 26 and the drum 52 isbrought to a stopat the position shown in Figure 5. The circuit. to thesecond counter 21 is energized through the solenoid switch 78.

. The second counter 21 closes the circuits to the clutches 62, 68. Thedrum 52 now moves slowly forward in the direction of the arrow shown onthe drum- 52 in Figure 5; this is accomplished by the counter 21energizing the clutch 62 so that the worm gear 58 slowly turns to windthe drum 52 forward. At the same time, the clutch 63 has been energized,whereby the hanking arms 18, 18

are rapidly rotated as the drum 52 moves slowly forward.

The longitudinal strands 76 are consequently rotated by the arms 18 anddraw the cord or rope 67 into transverse windings 77, as the feed 65moves slowly forward with the drum 52 in timed relation to the morerapid axial rotation of the arms. When a predetermined number oftransverse windings 77 have been applied to the longitudinal strands 76to complete the hank, the counter 21 which has all the while beensimultaneously driven by the chain 20, opens the circuits to disengagethe clutches 62, 63, thereby disconnecting the drum 52 and the arms 18,18 respectively from further motion producing drive and further rapidaxial motion producing driv'e. At the same time, the brake 64 is appliedcompletely stopping the apparatus. It is well to note at this time thatthe counter 21 stops with the circuits to the clutches 62 and 63 open.Consequently, in order to start the counter into motion again, at theproper time, it is necessary to close the circuit to these clutches 62,63 momentarily until the counter 21 again closes these circuits. This isaccomplished by the counter 26 in conjunction with the cam 79 and thesolenoid switch 78 which closes the open clutch circuits and starts thecounter 21 again. The counter 21 then closes the circuits to theclutches 62, 63 and the cycle starts again. When the motion of thecounter 21 is suflicient to close the circuit to the clutches 62, 63,the solenoid switch 78 drops oh the cam 79 and the auxiliary circuit isopen at the switch 78.

The completed hank is then removed from the arms 18, 18, and a secondcycle is started. The next cycle is started by the starter switch 75.

The hanks produced may be cut, and put aside. Or, if desired, they maybe permitted to remain together and placed, one after the other, as theyare formed, into the hank holder 80. The hank holder 80 is enteredthrough the passage 81 and rotates with the arms 18, 18. The counter 21operates the gear 15 and is connected to energize the brake 64 to stopthe arms 18, 18 at the end of the second part of the cycle (latitudinalwrapping). Since the brake is energized, a time delay switch 82 isincluded in the circuit which switch is adjustable to open the brakecircuit immediately after a sufficient lapse of time to enable the brake64 to stop the operations.

The control circuit shown in Figure 5 embodies the two counters 21, 26.These are standard items of commerce, being a species of electric switchin which a preselected number of revolutions opens or closes circuits.Thus when the starter switch 75 is operated, the counter 26 commences tomove and closes the circuit to the clutch 61. The motors 12 and 22 runcontinuously. The circuit to the clutch 61 is opened after a preselectednumber of turns and, the auxiliary circuits to the clutches 62 and 63are closed through the solenoid switch 78. This starts the counter 21into motion, closing the primary circuits to the clutches 62 and 63.

When the clutch 61 is engaged, the drum 52 revolves rapidly forlongitudinal winding. When the clutch 61 is disengaged and the clutches62 and 63 are engaged, the drum 52 revolves slowly and the arms 18, 18revolve rapidly for latitudinal wrapping. At the conclusion of apreselected number of turns, the counter 21 energizes the brake 64 andde-energizes the clutches 62 and 63. The cycle may thereafter berepeated at will.

The foregoing description is intended merely to illustrate an embodimentof my invention. Many changes may be made in the construction,selection, and arrangement of the parts, or the substitution of theirknown equivalents in form and function, and these are intended tubewithin the scope of the claims.
